New idea for hearing improvement in patients with hearing aids under background noise

August 3, 2014 - 10:00pm
(Neural Regeneration Research) Patients with implanted artificial cochlea often complain that they cannot recognize speech well in natural environments, especially if background of noise is present. Researchers think that a poor ability to localize sound in a complex auditory environment is responsible for the weak speech perception observed under these conditions.

Concerts on Yahoo make best of industry struggles

Sometimes the struggles of an industry can bring music to your ears. And your screens.

Apple closes acquisition of Beats music

August 1, 2014 - 9:28am
Apple said Friday it closed its $3 billion deal for Beats, the high-end audio equipment and streaming music service, a tie-up that could allow the iPhone maker to reach new audiences.

For bats and dolphins, hearing gene prestin adapted for echolocation

August 1, 2014 - 7:12am
A little over a decade ago, prestin was found to be a key gene responsible for hearing in mammals. A new study has shown that prestin has also independently evolved to play a critical role in the ultrasonic hearing range of animal sonar, or echolocation, to help dolphins navigate through murky waters or bats find food in the dark.

For bats and dolphins, hearing gene prestin adapted for echolocation

August 1, 2014 - 12:28am
A little over a decade ago, prestin was found to be a key gene responsible for hearing in mammals. Prestin makes a protein found in the hair cells of the inner ear that contracts and expands rapidly to transmit signals that help the cochlea, like an antique phonograph horn, amplify sound waves to make hearing more sensitivity.

For bats and dolphins, hearing gene prestin adapted for echolocation

July 31, 2014 - 10:00pm
(Molecular Biology and Evolution (Oxford University Press)) In a new study published in the advanced online edition of Molecular Biology and Evolution, Peng Shi, et al., have shown that prestin has also independently evolved to play a critical role in the ultrasonic hearing range of animal sonar, or echolocation, to help dolphins navigate through murky waters or bats find food in the dark.

Tapping Into Musical Memory

A new documentary, Alive Inside, exposes the connections between music and memory.

Effect of loud noises on brain revealed in study

July 31, 2014 - 8:25am
Prolonged exposure to loud noise alters how the brain processes speech, potentially increasing the difficulty in distinguishing speech sounds, according to neuroscientists. Exposure to intensely loud sounds leads to permanent damage of the hair cells, which act as sound receivers in the ear. Once damaged, the hair cells do not grow back, leading to noise-induced hearing loss.

Singing the same tune: Scientists develop novel ways of separating birdsong sources

July 31, 2014 - 8:10am
Researchers at the University of California, Los Angeles and the Chinese Academy of Sciences have pioneered a new study that could greatly improve current methods of localising birdsong data. Their findings, which ascertain the validity of using statistical algorithms to detect multiple-source signals in real time and in three-dimensional space, are of especial significance to modern warfare.

Research finds numerous unknown jets from young stars and planetary nebulae

July 31, 2014 - 7:56am
For many years astronomers have known that young 'protostars' drive supersonic jets of gas from their north and south poles. However, this is the first time that so many of them have been detected at once.

Singing the same tune: Scientists develop novel ways of separating birdsong sources

July 31, 2014 - 7:51am
A new study could greatly improve current methods of localizing birdsong data. The study demonstrates the validity of using approximate maximum likelihood (AML) algorithms to determine the direction of arrival (DOA) of birdsong sources.

Boat noise impacts development, survival of sea hares

July 31, 2014 - 7:50am
The development and survival of an important group of marine invertebrates known as sea hares is under threat from increasing boat noise in the world's oceans, according to a new study. Sea hares usually hatch from their eggs to swim away and later feed on toxic alga but this study found that when exposed to playback of boat noise, more eggs failed to develop and those that hatched were more likely to die.

Panasonic, Tesla to build big US battery plant

July 31, 2014 - 6:50am
(AP)—American electric car maker Tesla Motors Inc. is teaming up with Japanese electronics company Panasonic Corp. to build a battery manufacturing plant in the U.S. expected to create 6,500 jobs.

Nokia in wireless network deal with Panasonic

July 31, 2014 - 6:40am
(AP)—Finnish wireless equipment maker Nokia says it has a preliminary agreement to acquire part of the wireless network business of Japan's Panasonic Corp.

Boat noise impacts development and survival of sea hares

July 31, 2014 - 6:30am
While previous studies have shown that marine noise can affect animal movement and communication, with unknown ecological consequences, scientists from the Universities of Bristol and Exeter and the École Pratique des Hautes Études (EPHE) CRIOBE in France have demonstrated that boat noise stops embryonic development and increases larval mortality in sea hares.

UT Dallas study reveals effect of loud noises on brain

July 30, 2014 - 10:00pm
(University of Texas at Dallas) Prolonged exposure to loud noise alters how the brain processes speech, potentially increasing the difficulty in distinguishing speech sounds, according to neuroscientists at The University of Texas at Dallas.

Exploring 3-D printing to make organs for transplants

July 30, 2014 - 8:41am
Printing whole new organs for transplants sounds like something out of a sci-fi movie, but the real-life budding technology could one day make actual kidneys, livers, hearts and other organs for patients who desperately need them. Scientists are reporting new understanding about the dynamics of 3-D bioprinting that takes them a step closer to realizing their goal of making working tissues and organs on-demand.

Do your stem cells sound like cancer? While-you-wait, non-invasive cancer diagnosis by converting stem cell data into sound

July 29, 2014 - 10:38am
Converting stem cell data into sounds could enable GPs to make instant, non-invasive cancer diagnoses during a routine check-up. A recent study shows how data sonification (where data is conveyed as audio signals as opposed to visual illustrations such as graphs) can improve standard techniques currently used in spectroscopy stem cell analysis. What could this mean for cancer diagnostics?
